  The Ariane placed the Satmex 5 satellite into a 211km x 21516 km x 7.0 degree orbit from which the satellite was to use its on-board engine to reach geostationary orbit. Satmex 5 was operated by Satellites Mexicanos S.A. de C.V, which took over the Morelos constellation from Mexican Secretaria de Comunicaciones y Transportes. Satmex 5 replaced Morelos 2 and carried the XIPS ion engine station-keeping system.

• PAS 6B Spacecraft: HS 601. Mass: 3,475 kg.

  The Ariane third stage placed the PAS 6B into a 228 km x 35717 km x 7.0 degree orbit. The satellite�s on board rocket system will move it into its final geostationary position over South America. PAS 6B will provide direct TV broadcasting service in replacement of PAS 6, a Loral satellite which had problems with its solar arrays. The new satellite had 32 Ku-band transponders.

• Galaxy 10R Spacecraft: HS 601. Payload: Galaxy XR. Mass: 1,987 kg.

  Geosynchronous satellite launched to supplement Panamsat's Galaxy cable TV distribution constellation. It carried Ku and C band transponders and was to be stationed at 127 deg W. A replacement for Galaxy 10, lost on the first Delta 3 launch failure. Stationed at 123 deg W.

• Galaxy 4R Spacecraft: HS 601. Payload: Galaxy IVR.

  Galaxy 4R carried 28 Ku-band and 28 C-band transponders. After insertion in a standard 219 x 32007 km x 7.0 deg geostationary transfer orbit, Galaxy 4R's R-4D apogee engine raised orbit to 35765 x 35792 km x 0.1 deg by April 27 and was over 67 deg W by late April. Final destination was 99 deg W. The Galaxy satellites provide US domestic telecommunications services. 4R replaces the original Galaxy 4H which failed in May 1998, putting pagers out of action across the USA. Stationed at 99 deg W.

• N-SAT-110 Spacecraft: AS 2100.

  N-SAT-110, also known as Superbird 5, was jointly owned by SCC (Space Communications Corporation of Tokyo) and JSat (Japan Satellite Systems). SCC controlled the vehicle on orbit. The satellite carried 24 Ku-band transponders. By October 15 N-SAT-110 was in a 35610 x 35752 km x 0.1 deg orbit drifting past 109 deg E. Stationed at 110 deg E.
